GUARD FOR DOORS, WINDOWS, 80C.

SPECIFICATION forming part of Letters Patent No. 498,574, dated May 30, 1893. I

Application lerl September 27, 1892. Serial No. 447,008. (No model.)

T0 all whom t may concern: Be it known that I, LAURENCE F. RYAN, of New York city,in the county and State of New York, have invented a new and Improved Guard for lVindows, Doors,Y duc., Yof which the following is a full, clear, and exact description.

My invention relates to an improvement in guards for windows, doors, and other openings, and has for its object to provide a device of simple, d u rable and economic construction and capable of being conveniently and expeditiously fitted to any opening, and when so tted therein the guard will consti-tute a barrier, effectually preventing children, especially, from passing through the opening thus guarded.

Another obj ect of the invention is to vso construct the device that when not in use it may be folded to occupy but little room and in a manner to enable it to be readily transported The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanying drawings forming a part of this specication, in which similar figures and letters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the guard, one portion thereof being partly in section. Fig. 2 is a partial plan view of the guard in its folded position. Fig. 3 is a sectional View taken through one of the members, illustrating the manner in which two interlocking members are connected. Figeisa plan view of one of the end posts, and a partial plan and sectional view of the upper lever located in said post; and Fig. 5 is a detail View illustrating a slight modification in the shape of the locking mechanism.

In carrying out the invention the device is constructed in two sections A and B. The section A consists of an upright 10, constituting one end of the device. This upright is preferably in the shape of a U-bar, and may be of any desired length, and the back of the bar is provided with a series of spurs 11, adapted to enter into the wood-work, framing or opening which the device is adapted to cross. In the upright 10, between its side `three beingillustrated in the drawings.

members, levers 12, are fulcrumed. Any desired number of levers may be employed, The levers are made practically in the shape of a gun-ham mer, the upper lever being decidedly of this shape, and the pivotal point of the levers is at the lower end. Thus the upper lever is somewhat L-shaped, the short arm being uppermost, and the said arm extends some distance beyond the inner face of the standard or post. The levers are graduated "as to size, the lower lever being the smallest one; that is to say, each lever below the upper one is made shorter in both of its members, the intermediate lever extending a much less distance beyond the inner face of the standard than the upper one; and the lower lever, when three are employed, practically loses its angular shape and partakes more of a rectangular contour, almost the entire lever being located within the standard. In

the inner end of each lever a rod 13, is loycated,the central rod being firmly secured,

and the upper and lower ones adjustable; that is to say, the upper and lower rods are screwed into th'e levers so that they may be turned to present their rack surface either upward or downward. The upper and lower bars 13 have produced in what is normally their upper and lower faces respectively a series of teeth 14, the teeth constituting virtually a rack surface, as is best illustrated in Fig. 3.

The section B is alike in construction to the section A with the exception that instead of rods 13 being employed tubes l5, are used, the said tubes being of a diameter sufficiently large to receive the rods 13 of the opposed section, and the upper and lower tubes 15 of the section B have brackets secured thereon, designated respectively as 16 and 17, the bracket of the upper tube facing upward and that of the lowertube downward. Between the members of these brackets an opening 18,

ings 18 in the tubes a locklever C, is pivoted,

the said lock lever comprising essentially a IOO disk-shaped head 19 provided with teeth adapted to engage with the rack surfaces of the bars 13, the said disk head being eccentrically pivoted so that it acts in the capacity of a cam, and the disk is provided with an attached handle 20, which curves downward to an engagement with the tube in which the lever is pivoted when the lever is in its locked position, as shown in Fig. 3; and the free extremity of the handle 20, is made somewhat semi-circular in cross section so as to lit down closely upon the exterior surface of the tube. If in practice it is found desirable the handles of the lock levers at their lower ends may be serrated or threaded, as shown also in Fig. 3, to receive a sleeve 2l, loosely mounted upon the tube, the said sleeve serving to lock the lever in such manner that it can not be readily raised, and if deemed advisable the free end of each lever may be provided with downwardly extending ears 22, at each side, as shown in Fig. 5, which ears are provided with apertures 23. Thus when the lever is in its locked position a pad-lock may be used in connection therewith, eifectually preventing the adjustment of the sections being tampered with.

In the manipulation of the device, the bars 13 of the section A are lmade to enter the tubes 15 of the section B, the lock levers be'- ing thrown upward so as to disengage their teeth from the rack surfaces of the bars. The first adjustment of the two sections is to render the device of less width than the opening in which it is to be itted; it is then placed in the opening and the standards 10 are forced apart until their spurs 11 enter the casing around the opening. When this is effected the lock levers are pressed to an engagement with the tubes, causing their teeth to engage with the rack surfaces of the bars, and the levers are then locked, either by the pad-lock referred to or by the sleeve 21, in such a man- Vner that children can not elevate the levers and thereby disturb the adjustment of the device.

When the device is not in use, as heretofore stated, it may be folded very compactly for shipment or for storage, and when folded will appear as in Fig. 2. When the device is folded, one section is withdrawn entirely from engagement with the other, and the upper and lower rods 13, are turned in a manner t-o reverse the position of their rack surfaces. One entire section is then reversed, that is, what constitutes the bottom when the device is in use is made to constitute the top, and in this position the two sections are again connected by causing the bars to enter the tubes, and the two sections are thereupon forced together until the rods will have passed almost practically their entire len gt-h within the tubes. As the upper and lower rods 13 of the section A have been reversed or turned,

. smooth surfaces o'f the rods are presented to the lock levers, and consequently the movement of the rods in the tubes is not interfered with. The parts being in this position the levers in one standard will be in their normal position while the levers in the opposite standard will be reversed as to position, thus enabling the two standards to be folded one down and the other up, and the connected tubes and rods will fold parallel one with the other, this parallel position being possible by reason of the graduations in the sizes of the levers 12.

It will be observed that a device of this character may be expeditiously and conveniently applied to permanently or temporarily close any opening against the passage of a child, or of an adult, if the device is made high enough, or of any animal, and that the construction of the device is such as to render it exceedingly simple and economic, and,

further, when not in use, it may be disposed of in but little space.

'Having thus described my invention, I claim as new and desire to secure by Letters Patent* v 1. A guard for windows, doors, Src., comprising two sections, each section being constructed with an end standard and levers fulcrumed in said standards, one section having attached to the free end of its levers tubes, and the other section rods adapted to slide in said tubes, the rods being provided with rack surfaces and the tubes with openings over which lock levers are fulcrumed adapted to engage the rack surfaces of the rods, substantially as shown and described.

2. A guard for windows, doors, &c., constructed in two telescopic, folding sections, each section comprising an end standard and essentially angular levers fulcrumed at one end of the standards, which levers are graduated in size, the levers of one section having tubes connected therewith and the levers of the opposite section having rods secured thereto adapted to enter the tubes, and a locking device carried by one section and engaging with the other, substantially as and for the purpose specified.

3. `In a guard for windows, doors, &c., the combination, with a section comprising an end standard having spurs attached, angle levers fulcrumed at one end'of their members to the standard, said levers being graduated in size, and rods attached to the levers, the upper and lower rods being held to turn in the levers and provided with rack surfaces, of a second section also comprising an end standard provided with spurs, angle levers pivoted to the standard and graduated as to size, tubes attached to the leversand adapted to have telescopic connection with the rods, a lock lever carried by the upper and lower tubes and engaging with the rack surfaces of IIO the rods, and a locking device, substantially
